Method and apparatus for feeding back data transmission acknowledgement and communication system

An apparatus for feeding back data transmission acknowledgement, comprising:

• a memory that stores a plurality of instructions;
• and
• processor circuitry that couples to the memory and is configured to execute the instructions to:
• receive feedback information of hybrid automatic repeat request (HARQ) processes scheduled to perform data transmission acknowledgement at a current moment and transmitted by a user equipment;
• order the HARQ processes scheduled to perform data transmission acknowledgement at the current moment;
• and
• determine whether data of the scheduled HARQ processes are successfully transmitted according to a situation of data transmission of the scheduled HARQ processes after ordering indicated by the feedback information.

A communication system, comprising:

• a first apparatus comprising:
• a receiver configured to receive feedback information of hybrid automatic repeat request (HARQ) processes scheduled to perform data transmission acknowledgement at a current moment and transmitted by a user equipment;
• and
• processor circuitry configured to
• order the HARQ processes scheduled to perform data transmission acknowledgement at the current moment, and
• determine whether data of the scheduled HARQ processes are successfully transmitted according to a situation of data transmission of the scheduled HARQ processes after ordering indicated by the feedback information;
• and
• a second apparatus comprising:
• processor circuitry configured to,
• when a user equipment is scheduled to feed back data transmission acknowledgement in a current uplink transmission channel, order more than one hybrid automatic repeat request (HARQ) processes scheduled to perform data transmission acknowledgement at a current moment;
• and
• sequentially indicate whether data transmissions of the scheduled HARQ processes after ordering are successful or not via consecutive bits in feedback information bits, the number of the consecutive bits being identical to the number of the scheduled HARQ processes;
• and
• a transmitter configured to transmit feedback information to a network side via the uplink transmission channel.
